I have used magnets to eliminate stubborn pain. I think one was something torn in my shoulder. After a few months of chronic pain I strapped on a magnet from a set I had gotten as a gift. After wearing it daily, the pain vanished after maybe a week never to return. I had a similar stubborn pain in my wrist for a few months. Applied the magnet and after a week or so it too vanished and never returned. I don't know what it does or how but I'm a believer.
